In the specific implementation, gateway can continuously send multiple data frames to terminal.For example, gateway is according to data The frame identification order of frame, sends data frame successively, after a data frame is sent, and withouts waiting for terminal for current data The reception confirmation message that frame is returned, you can continue to send next data frame.In another example, gateway after a data frame is sent, After can waiting for a period of time, regardless of whether receiving reception confirmation message, continue to send next data frame.
Those skilled in the art can realize continuously transmitting for multiple data frames in different ways as needed, to protect Card remains to continue to send next data frame in the case where terminal does not return to reception confirmation message.
Terminal can return to the reception confirmation message for data frame after data frame is received.Wherein, confirmation is received to disappear Breath can point to the data frame of setting quantity.For example, terminal can return to one for multiple data frames received receives true Recognize message, and need not be only limited to return to a reception confirmation message for a data frame.
In practical application, terminal can be according to its residing network environment, it is determined that the reception confirmation message returned points to one Individual data frame, is also directed to multiple continuous data frames.For example, network environment preferably in the case of, be suitable for weighing currently Send out data frame multiple, the frame identification of multiple data frames can be added in single reception confirmation message, and in network environment phase In the case of undesirable, it is not appropriate in current retransmission data frame, then can adds single in single reception confirmation message The frame identification of individual data frame.So that gateway can set the data frame of quantity according to pointed by receiving in confirmation message, In the case that data frame sends failure, using the data frame re-transmission mode for being matched with network environment residing for terminal.
Step 102, after multiple data frames are continuously transmitted, the history do not pointed to by the reception confirmation message is retransmitted Send data frame.
In the specific implementation, the data frame pointed by the reception confirmation message that gateway can be returned according to terminal, determines history In the multiple data frames sent, the data frame for being defined as sending failure not pointed to by reception confirmation message.Continuously transmitting After multiple data frames, it may be determined that after the data frame for sending failure, and retransmit the data frame of the part.
It is a kind of wherein to retransmit the specific embodiment party that the history do not pointed to by the reception confirmation message sends data frame In formula, can when single reception confirmation message points to a data frame, after whole data frames is sent, for The history transmission data frame for not receiving reception confirmation message is retransmitted.For example, list of the gateway for one data frame of sensing Individual reception confirmation message, can be after some currently transmitted data frame, if being not received by the reception confirmation for the data frame The data frame, then can be labeled as number of failures according to frame, and continue to send next data frame by message.By whole numbers After being sent according to frame, the number of failures of mark is re-transmitted to terminal according to frame.
The history do not pointed in another repeating transmission by the reception confirmation message sends the embodiment of data frame In, multiple continuous data frames, after multiple data frames are continuously transmitted, pin can be pointed in the single reception confirmation message Retransmitted to sending data frame currently without the history for receiving reception confirmation message.For example, continuously transmitting multiple data frames Afterwards, if currently without receiving the reception confirmation message of pointing to the plurality of continuous data frame, can will be the plurality of continuous Data frame is re-transmitted to terminal.
Those skilled in the art can be actually needed to retransmit not by going through that reception confirmation message is pointed in different ways History sends data frame, and the embodiment of the present invention is not restricted to this.
According to embodiments of the present invention, gateway continuously transmits multiple data frames to terminal, and the reception that receiving terminal is returned confirms Message, according to the single reception confirmation message for pointing to the data frame for setting quantity, can disposably confirm to set the hair of quantity Successful data frame or number of failures are sent according to frame, and is retransmitted for the data frame for sending failure, thus, is ensureing that data are complete While whole property, on the one hand, gateway is that next data frame can be transmitted without waiting for the reception confirmation message of terminal, shortens data The time that transmitting procedure expends, so as to shorten the time that terminal is stayed awake for, save the process resource of terminal consumption； On the other hand, terminal need not return for the data frame each received and receive confirmation message, reduce transmission processing, save The process resource of terminal consumption.Therefore, in whole data transmission procedure, the process resource that terminal is consumed is saved.
Embodiment two
Another data transmission method provided in an embodiment of the present invention is discussed in detail.
Reference picture 2, shows a kind of step flow chart of data transmission method of the embodiment of the present invention two.
Step 201, multiple data frames are continuously transmitted to terminal, receives the terminal and be directed to the reception that the data frame is returned Confirmation message；It is described to receive the data frame that confirmation message points to setting quantity.
Alternatively, it is described to include following sub-step the step of continuously transmit multiple data frames to terminal：
Sub-step S11, multiple data frames are split into by packet to be sent, and moving at least one has the number of setting range According to mark window.
Sub-step S12, the data frame in the data markers window is sent to the terminal.
It should be noted that above-mentioned packet to be sent can be to be sent to the firmware that terminal supplies terminal system to upgrade. In the specific implementation, packet can be split into multiple data frames.A transmission window can be set, multiple data frames are inputted To the transmission window.For sending multiple data frames on window, the data markers window of a setting range can be initialized.
Can by the data markers window at set time intervals with slide amplitude, enter along the orientation of data frame Row movement.Data markers window after movement can mark several data frames, by labeled some data frames send to Terminal.
Alternatively, it is described to include following sub-step the step of continuously transmit multiple data frames to terminal：
Sub-step S21, according to the frame identification order of data frame, sends multiple data frames to the terminal successively.
In the specific implementation, can putting in order according to the frame identification of multiple data frames to be sent, end is sent to successively End.In practical application, frame identification can be the frame number of data frame, can be transmitted according to the size order of frame number.
In practical application, before the step 201, methods described can also include：
The summary info of the data frame is sent to the terminal.
When not receiving the summary verification success message that the terminal is returned in the range of setting time, then stop sending number According to frame.
In the specific implementation, gateway can send what is currently sent to terminal in advance before the transmission of data frame is carried out The summary info of multiple data frames, carries out preliminary verification for terminal and obtains the frame mark of this total data frame to be transmitted The information such as knowledge.In practical application, summary info can be compression firmware and MD5 (Message Digest Algorithm MD5, Message Digest Algorithm 5) the Meta information (Meta Information, metamessage) that generates after verification.
After terminal-pair summary info is verified, summary verification success message can be accordingly returned according to check results or is plucked Verify failed message.Verifying successfully can then start the transmission of data frame, and verification failure does not start data frame transmission then.It is actual In, timer can be set for the summary info sent, monitoring timing is carried out to return to message to terminal.If it exceeds Certain time does not still receive the verification success message for summary info, then does not start data frame transmission.
Step 202, the verification failed message that the terminal is returned for the data frame of verification failure is received.
Step 203, the corresponding data frame of the verification failed message is retransmitted.
Terminal can be verified for the data frame received, to ensure that the content of data frame is correctly lossless.If verification is lost Lose, terminal can be with back-checking failed message to gateway.Due to verification failed message can be received, show the current net of terminal Network environment is normal, therefore gateway can immediately be retransmitted for the data frame of verification failure, and without waiting for total data Frame is retransmitted again after sending.If verifying successfully, terminal can directly return to reception and confirm message to gateway, so that gateway can continue Send next data frame.
Step 204, after multiple data frames are continuously transmitted, the history do not pointed to by the reception confirmation message is retransmitted Send data frame.
Alternatively, the step 204 can include following sub-step：
Sub-step S31, when the single reception confirmation message points to a data frame, is sent in whole data frames Afterwards, whole history transmission data frame that confirmation message is received for not receiving is retransmitted.
When the single reception confirmation message that gateway is received points to a data frame, corresponding data frame re-transmission can be used Mode is retransmitted.Specifically, after whole data frames have been sent, it can be searched in whole history send data frame Data frame is sent as number of failures according to frame in the absence of the history for receiving confirmation message, and number of failures is sent to institute according to frame State terminal.Or, after some currently transmitted data frame, if being not received by the single reception confirmation for a data frame One data frame flag can be then number of failures by message according to frame, and continue to send next data frame.Sending After whole data frames, in the data frame that history is sent, search labeled as number of failures according to frame, it is all sent out again Deliver to terminal.
Alternatively, it is described to include the step of continuously transmit multiple data frames to terminal：
Send a data frame, and monitor send data frame after setting time in the range of whether receive reception confirmation disappear Breath；
If so, then continuing to send next data frame；
If it is not, it is number of failures according to frame then to mark currently transmitted data frame, and continue to send next data frame.
In the specific implementation, gateway can set one after a data frame is sent for the data frame of each transmission Timer, confirmation message progress monitoring timing is received to be returned to terminal.If gateway receives reception in the range of setting time Confirmation message, then continue to send next data frame.If still showing end to receive reception confirmation message in the range of setting time End may be not good due to network environment and successful data reception frame or can not can not successfully return to reception confirmation message.Therefore can be with The current data frame of mark is number of failures according to frame, and continues to send next data frame.
In practical application, whole history that confirmation message is received for not receiving of one of which send data frame and carried out In the embodiment of repeating transmission, the transmission number of failures can be monitored according to whether being received in the range of the setting time after frame To reception confirmation message；If so, then continuing to send next number of failures according to frame, if it is not, then retransmitting current transmission failure Data frame.More specifically, being sent by total data frame to terminal, it can be retransmitted for sending the data frame of failure. In retransmission process, if receiving reception confirmation message in the range of setting time, continue to send next data frame.If not connecing Reception confirmation message is received, then can resend current data frame.
, may be not good because of the network environment residing for terminal in actual data transmission applications scene, cause to send Data frame returns to reception confirmation message failure.For example, there are other users to be passed by beside the terminal carried out data transmission, The network signal of terminal is disturbed, or, there is fluctuation etc. in current network signal.In the case where network environment is not good, If gateway retransmits the data frame for sending failure always, the time-consuming longer of whole data transfer can be caused, terminal is also correspondingly Need to keep longer wake-up states.Stay awake for needing to consume the substantial amounts of process resource of high power consumption terminal for a long time, most The service life of terminal may be influenceed eventually.
According to embodiments of the present invention, it is not good in network environment residing for terminal by continuously transmitting multiple data frames to terminal In the case of receiving reception confirmation message, continue the next data frame of transmission and be extremely sent to total data frame, Network environment residing for terminal recover it is normal after retransmission data frame again.So as to reduce the number of retransmissions in the case where network environment is not good The time expended according to frame, the time that terminal is stayed awake for also accordingly is reduced.While guaranteeing data integrity, save The process resource that terminal is consumed.Wake-up states processing data frame need not be in for a long time by being additionally, since terminal, improve terminal Service life.
Alternatively, the step 204 can include following sub-step：
Sub-step S41, when the single reception confirmation message points to multiple continuous data frames, for currently without receiving The history transmission data frame for receiving confirmation message is retransmitted.
When the single reception confirmation message that gateway is received points to multiple continuous data frames, corresponding data can be used Frame re-transmission mode is retransmitted.Specifically, after multiple data frames are currently continuously transmitted, if it is multiple continuous to be not received by sensing Data frame reception confirmation message, then the plurality of continuous data frame can be re-transmitted to terminal.If current continuous Send after multiple data frames, receive the reception confirmation message for pointing to multiple continuous data frames, then can be directed to the plurality of number According to frame flag to send successful data frame, and continue to send multiple continuous data frames of next group.
In actual applications, one timer can be set for the data frame each sent, with to receiving confirmation message Time of return carry out timing monitoring.For continuously transmitting the situation of multiple data frames, if still do not connect within a certain period of time Receive the single reception confirmation message for multiple continuous data frames, then it is assumed that the multiple data frames continuously transmitted before are sent out Failure is sent, the plurality of data frame for sending failure can be retransmitted.
Alternatively, the step of reception confirmation message that the reception terminal is returned for the data frame, can include Following sub-step：
Sub-step S51, receives the terminal for reception confirmation message of multiple data frames correspondence added with frame identification；
Methods described can also include：
By the data frame corresponding to multiple frame identifications in the reception confirmation message, labeled as transmission successful data frame.
In the specific implementation, terminal is after multiple data frames are received, can be by the frame identification of the multiple data frames received Added to confirmation message is received, gateway is then returned to.Gateway receives the single reception confirmation message for pointing to multiple data frames Afterwards, corresponding data frame can be searched according to the multiple frame identifications wherein added, by multiple data frames of lookup labeled as transmission Successful data frame.
Alternatively, the step of reception confirmation message that the reception terminal is returned for the data frame, can include Following sub-step：
Sub-step S61, receives the terminal and confirms to disappear for newest reception of the reception data frame added with target frame identification Breath and lookup configured information；
Methods described can also include：
According to the lookup configured information, the history transmission data frame that frame identification is less than target frame identification is searched, is labeled as Send successful data frame.
In the specific implementation, terminal is after multiple data frames are received, can be by the frame identification of recently received data frame As target frame identification, added to confirmation message is received together with searching configured information, gateway is then returned to.Gateway is received , can be according to the target frame mark searched configured information and wherein added after the single reception confirmation message for pointing to multiple data frames Know, in the data frame being transmitted across before this, the data frame that frame identification is less than target frame identification is searched, by multiple data frames of lookup Labeled as transmission successful data frame.
In actual data transmission applications scene, gateway can continuously transmit multiple data frames at a time interval to end End, and timer is set for the data frame each sent, the time-out time of setting can be T1.Terminal is receiving a data After frame, even if to data frame check success, reception confirmation message can not also be returned immediately, but according to time-out time T1 and Return to a reception confirmation message spent time T2 and determine current stand-by time (T1-2*T2).If received in stand-by time To more data frame, then after stand-by time terminates, the reception for returning to the target frame number added with the data frame finally received is true Recognize message.Gateway is received after the reception confirmation message, then frame number can be less than to the timer of multiple data frames of target frame number Closed, show the data frame of the part to send successful data frame, and continue to send follow-up multiple data frames.Example Such as, gateway have sent successively frame number be 1 to 10 data frame to terminal, in the reception confirmation message received be added with frame number 10, Then it is considered that frame number sends success for 1 to 10 data frame.
Alternatively, the sub-step S61 can include：
In the range of setting time after currently transmitted data frame is listened to, reception confirmation message is not received by, then is looked into Look for frame identification to be less than the frame identification of currently transmitted data frame and be not labeled as sending multiple history transmission of successful data frame Data frame, is retransmitted as number of failures according to frame.
In the specific implementation, after gateway have sent multiple continuous data frames, if being not received by reception confirmation message, Frame identification that can be according to the data frame sent recently, searches the data frame sent less than multiple history of the frame identification, is looking into In the data frame looked for, it will can be not labeled as sending the data frame of successful data frame, be carried out as the data frame for sending failure Retransmit.
According to embodiments of the present invention, by continuously transmitting multiple data frames to terminal, a sensing is returned to by terminal multiple The reception confirmation message of data frame, so that terminal need not return to multiple reception confirmation messages for each data frame respectively, is being protected While integrity of verified data, the process resource that terminal is consumed is saved.Moreover, terminal can provide more process resources Used for other functions, improve the overall treatment efficiency of terminal.
In practical application, if continued labelling number of failures is more than default threshold according to the number of times or data frame re-transmission number of times of frame Value, then stop sending data frame.Because in actual application scenarios, it is understood that there may be it is not good network environment residing for terminal, one Situation about can not directly recover.In this case, it is possible to can cause continuously to send data frame failure, if having attempted to retransmit Data frame can then expend the process resource of terminal.Therefore, it is super labeled as the number of times for sending failure when being continuously directed to multiple data frames When crossing certain threshold value, or data frame re-transmission number of times exceed certain threshold value when, can stop send data frame, exit this data Frame sends task.
In practical application, methods described can also include：Receive the data frame request message of the terminal；The data frame Request message includes the frame identification for the reception failure data frame that the terminal is recorded.
Frame identification in the data frame request message sends the reception failure data frame to the terminal.Terminal Can according to the frame identifications of all data frames to be sent in the data transfer task of this in summary info, or, according to multiple institutes The data frame lacked in data frame is received, the data frame of reception failure is determined and records its frame identification, the frame identification is added to Data frame request message is simultaneously sent to gateway, by gateway by corresponding data frame re-transmission to terminal.
Gateway and terminal record the data frame for sending failure and the data frame of reception failure respectively, pass through terminal request gateway The mode of the data frame of missing is retransmitted, while avoiding increasing the process resource of terminal, data transfer is further ensured Integrality.
It should be noted that the history that the repeating transmission that the embodiment of the present invention is provided is pointed to by the reception confirmation message Some embodiments of data frame are sent, can both be used alone in actual data transmission applications scene, and can also combine Applied for a kind of data transfer mode, can play saving terminal while guaranteeing data integrity and consume processing money The effect in source.For example, for multiple data frames continuously transmitted, according to the reception confirmation message of the single multiple data frames of sensing Multiple data frames are marked to send successful data frame；, can be by the plurality of data frame mark if do not receive reception confirmation message Number of failures is designated as according to frame, is retransmitted again after total data frame is sent.Those skilled in the art can be according to reality The data transmission method of the independent or above-mentioned offer of connected applications is provided.
In actual data transmission applications scene, the terminal of different power consumption is applied to different data transfer modes.Such as High power consumption terminal is suitable to avoid being in wake-up states for a long time, and low-power consumption terminal is suitable to reduction and returns to time for receiving confirmation message Number.
Therefore, according to embodiments of the present invention, terminal can return to corresponding sensing one according to the power consumption condition of itself The single reception confirmation message of individual data frame or multiple data frames.For high power consumption terminal, it can make it that high power consumption terminal need not Wake-up states processing data frame is in for a long time, improves the service life of high power consumption terminal.For low-power consumption terminal, Wu Xufen Safety pin returns to multiple reception confirmation messages to each data frame, saves process resource, it is supplied to provide more process resources He uses function, improves the overall treatment efficiency of low-power consumption terminal.So as to so that gateway, which can automatically switch, adapts to terminal work( The data transfer mode of consumption is consumed, flexibility and the adaptability of data transfer is improved.
It should be noted that in practical application, corresponding data transfer can be selected previously according to the power consumption situation of terminal Mode, and the reception confirmation message that need not be returned according to terminal is switched over.
Deeply understand the embodiment of the present invention for the ease of those skilled in the art, carried out below with reference to specific implementation example Explanation.
Fig. 7 shows a kind of step flow chart of transmission data frame of the embodiment of the present invention.It can be seen that gateway can be with Forward abstract information meta first carries out preliminary check to terminal, judges whether to receive ACK in the range of setting time, if super When receive then exit this transformation task, start if being properly received send data frame.Often sending a data frame can then set A transmission timer is put, judges whether to receive ACK in the range of setting time, marks and does not send if received over time currently The frame number of successful data frame, and send next data frame；For the ACK received, judge that terminal-pair received data frame is carried out The check results added after verification, if receiving the successful ACK of verification, directly transmit next data frame, if receiving verification The ACK of failure, then retransmit current data frame, and set transmission timer for the data frame currently retransmitted.It is complete sending After the data frame in portion, mark is not sent into successful data frame and retransmitted.In above process, it is continuous if there is reception ACK The situation of time-out, then exit this transformation task.After total data frame is successfully transmitted, then this transformation task is completed.
Fig. 8 shows the step flow chart of another transmission data frame of the embodiment of the present invention.It can be seen that gateway connects Supervention send multiple data frames to terminal, and a transmission timer can be set by often sending a data frame, be judged whether in setting ACK is received in time range, current multiple data frames are retransmitted if received over time or verification failure；Verified into if receiving The ACK of work(, then continue to continuously transmit multiple data frames.In above process, if there is a situation where to receive the continuous time-out of ACK, Exit this transformation task.After total data frame is successfully transmitted, then this transformation task is completed.
Embodiment three
Another data transmission method provided in an embodiment of the present invention is discussed in detail.
Reference picture 3, shows a kind of step flow chart of data transmission method of the embodiment of the present invention three.
Step 301, multiple data frames that gateway is continuously transmitted are received.
Step 302, for multiple data frames of reception, the reception confirmation message for the data frame for pointing to setting quantity is returned, The history do not pointed to by the reception confirmation message is retransmitted after multiple data frames are continuously transmitted for the gateway and sends number According to frame.
In the specific implementation, terminal can receive multiple continuous data frames of gateway transmission, and return for setting number The single reception confirmation message of the data frame of amount, retransmits the history do not pointed to by the reception confirmation message for gateway and sends number According to frame.Gateway retransmits the embodiment that the history do not pointed to by the reception confirmation message sends data frame, can be with pin Single reception confirmation message to pointing to a data frame, after whole data frames is sent, for not receiving reception The history of confirmation message sends data frame and retransmitted, or, the single reception for pointing to multiple continuous data frames can also be directed to Confirmation message, when not receiving reception confirmation message, for sending data currently without the history for receiving reception confirmation message Frame is retransmitted.
In practical application, methods described can also include：
Monitor whether the current setting time scope received after data frame receives next data frame.
If it is not, then marking next data frame to be reception failure data frame.
In the specific implementation, terminal can set timer for currently received data frame, to be connect to next data frame Monitoring timing is carried out between time receiving.Because gateway sends continuous multiple data frames, according to the frame identification of currently received data frame The frame identification of next data frame can be determined.Therefore, do not receive next data frame in the range of setting time, then can be directed to down The frame identification mark reception failure data frame of one data frame.
In practical application, methods described can also include：
Verify the data frame received.When verifying failure, the verification failed message for the data frame of verification failure is returned Gateway is back to, corresponding data frame is retransmitted according to the verification failed message for the gateway., then can be direct when verifying successfully Return and receive confirmation message.Because gateway can receive verification failed message, show that the current network environment of terminal is normal, because This gateway can for verification failure data frame be retransmitted immediately, and without waiting for total data frame send after weigh again Hair.
In practical application, methods described can also include：
When the number of times of continued labelling reception failure data frame is more than predetermined threshold value, then stop receiving data frame.
In practical application, it is understood that there may be the situation that network environment residing for terminal is not good, can not recover always.In this feelings Under condition, it may result in the continuous data frame that receives and fail, the processing of terminal can be expended if having attempted to receive data frame Resource.Therefore, when being continuously directed to number of times of multiple data frames labeled as reception failure more than certain threshold value, it can stop receiving Data frame, exits this data frame receipt task.
In practical application, methods described can also include：

In practical application, for a data frame being currently received, return recording has received the frame identification of data frame Reception confirmation message；Or, for the multiple continuous data frames received in the range of setting time, return recording has most The reception confirmation message of the new frame identification for receiving data frame or the total data frame received.
In the specific implementation, the data frame that can be received for each, returns to a reception confirmation message.Or, for The multiple data frames received in the range of setting time, by the complete of the frame identification of the data frame received recently or the plurality of data frame Portion's frame identification returns to gateway added to reception confirmation message.
In practical application, the data frame can carry whether being sent for monitored data frame for gateway setting fails Setting time scope, terminal can search the setting time scope from currently received data frame.
For example, gateway can set a timer for the data frame each sent, the time-out time of setting can be T1, as monitored data frame send whether fail setting time scope.
Terminal can find the setting time scope after data frame is received.Terminal can be according to the setting time Scope and every time return receive the time spent by confirmation message, it is determined that current stand-by time.
For example, terminal is after a data frame is received, even if to data frame check success, can not also immediately return and connect Receive confirmation message, but according to time-out time T1 and when returning to one and receiving confirmation message spent time T2 and determine current standby Between (T1-2*T2).
Terminal is directed to the one or more data frames received in stand-by time, returns and receives confirmation message.
For example, gateway have sent data frame that frame number is 1 to 10 to terminal successively, and terminal is received in stand-by time Frame number is 1 to 5 data frame, can be directed to the data frame finally received in stand-by time, and frame number 5 and lookup are indicated into letter Breath, which is added to, to be received in confirmation message, or, frame number 1 to 5 is added to and received in confirmation message.By the reception confirmation message Gateway is returned to, gateway according to the reception confirmation message, can confirm that 1 to 5 data frame is properly received by terminal.
According to embodiments of the present invention, gateway continuously transmits multiple data frames to terminal, and the reception that receiving terminal is returned confirms Message, according to the single reception confirmation message for pointing to the data frame for setting quantity, can disposably confirm to set the hair of quantity Successful data frame or number of failures are sent according to frame, and is retransmitted for the data frame for sending failure, thus, is ensureing that data are complete While whole property, on the one hand, gateway is that next data frame can be transmitted without waiting for the reception confirmation message of terminal, shortens data The time that transmitting procedure expends, so as to shorten the time that terminal is stayed awake for, save the process resource of terminal consumption； On the other hand, terminal need not return for the data frame each received and receive confirmation message, reduce transmission processing, save The process resource of terminal consumption.Therefore, in whole data transmission procedure, the process resource that terminal is consumed is saved.
Deeply understand the embodiment of the present invention for the ease of those skilled in the art, carried out below with reference to specific implementation example Explanation.
Fig. 9 shows that a kind of return of the embodiment of the present invention receives the step flow chart of confirmation message.It can be seen that eventually End can carry out preliminary verification and inspection for the summary info meta received, and return to the ACK comprising check results to net Close, with the transmission of trigger data frame.Whether terminal can be monitored receives data frame in the range of setting time, if being properly received To data frame, then ACK for one or more successful data reception frames is returned to gateway；If received over time, mark not into The data frame that work(is received, and keep holding state.If there is continuous received over time, record and all connect not successfully This transformation task of the data frame backed off after random of receipts.If having been received by after all data frames, this transformation task is completed.
